I've been diving for a long time but I still can't help but say: You study every day about L2, cross-chain, which is faster and cheaper, but if you don't revoke that "contract unlimited authorization" in your wallet, it's really like sleeping with the door open... To put it simply, giving authorization is like holding a long-term key; the project team may not be malicious, but you never know when a front-end might be hooked with a phishing link, or when a contract/permission might have some tricks, and then your assets are no longer yours. Recently, hardware wallets are out of stock, phishing is on the rise, everyone's security awareness has improved, but don't just focus on seed phrases—take some time to review the authorizations of your frequently used addresses. Revoke what you can, and don't keep unused permissions. Anyway, for new projects, I usually only give "use as much as needed," which is a bit more trouble but gives peace of mind.
